I am not sure if this is portable. It will probably not work with MSVC, for example.
Kitware suggests adding language standards to targets such as
target_compile_features(HIOP PRIVATE cxx_std_17)My understanding is that the built-in target cxx_std_17 is supposed to add correct flags for the compiler of your selection.

I doubt it is going to be an issue, because ExaGO only links to HiOp.

after checking others' code, e.g., RAJA, MFEM, etc..., I don't think I need to specify -std=c++17 or target_compile_features. Just pushed another commit for review.
